In addition, as the transparent resin for forming the 2nd transparent resin layer 42, as long as Δ L*
awith Δ L*
bpoor (| Δ L*
a-Δ L*
b|) be above-mentioned scope, but be preferably heated to after 230 ℃ in temperature, in rapid chilled situation and slow cool down situation under turbidity (haze) be worth in 0～60 scope, more preferably in 35～55 scope.Be the transparent resin in above-mentioned scope by using turbidity value, can further improve the effect suppressing because causing tone to change in the gonorrhoea of carrying out embossing and add man-hour.
In the present embodiment, as the method that forms surface resin layer 40 on bond layer 30, be not particularly limited, for example, can list the film-stack of utilizing thermal welding etc. to be used in the film of the 1st transparent resin that forms the 1st transparent resin layer 41 and being used to form the 2nd transparent resin of the 2nd transparent resin layer 42, and the stacked film obtaining is adhered to method on bond layer 30 etc.Wherein, the film of the film of the 1st transparent resin and the 2nd transparent resin can be both after film forming without extension state, can be also along uniaxial extension or along twin shaft extend state.
And, by substrate resin layer 10 side of the decorating film 100 forming are like this layered on base material, can obtain decorative panel.In addition, conventionally, form the decorating film 100 of decorative panel on being layered in base material before or be layered on base material after, the state that is for example heated to 230 ℃ of left and right with temperature from outermost the 1st transparent resin layer 41 sides that form decorating film 100 utilizes dandy roll to compress decorating film 100, implements thus embossing processing.
In addition, as the base material stacked with decorating film 100, be not particularly limited, for example, can list the metallic plates such as steel plate, tin free steel sheet, aluminium alloy plate, galvanized steel plain sheet, zinc-cobalt-molybdenum composite deposite steel plate, zinc-nickel alloy coating steel plate, zinc-iron alloys clad steel sheet, alloy galvanized steel plate, zinc-aluminum alloy coating steel plate, zinc-aluminium-magnesium alloy clad steel sheet, nickel-clad steel plate, copper plated steel or stainless-steel sheet.
